Johnrg87: Thanks for the feedback, man! I think we're on the same page. Perhaps this isn't truly dithering, but the definition seemed to make sense to me based on what was going on. I am running the break-in DVD when I can, but since I have it's in the family room, it's certainly seeing normal viewing action, too (albeit at low picture settings). The brightness definitely makes a big difference, and I'll have to play more with the sharpness to see if it makes any difference. The source doesn't seem to matter at all for this particular phenomenon. Seen on anything from crappy Wii, average Dish HD, 360 1080i component, and superb Wall-e Blu-ray (PS3) sources. Again, though, it's only within a few feet that you can even see the dithering effect.
I'm glad to hear about the green push drop, though, since that is something that also catches my eye. As for the dots, yes, it's only when you're less than a few feet away---and honestly, I feel silly that it even bothers me, since at normal viewing distance I can't see it at all. I'm just a bit obsessive with this stuff!
Overall, the PQ is just astounding to me, given what I paid for the thing, so I shouldn't be complaining. The "dithering" is minor, the green push is slightly annoying, but hopefully working itself out with break-in, and the Wii issue is just weird. Aside from those issues, I have no complaints with the set. I appreciate all the feedback, and am glad the thread was started.
I found the Ruiz settings to try our on the XXS1 thread, but where is the original post? I'm having trouble finding the actual Ruiz post anywhere.
